Plex NAS Advice

Hi all,

I’m looking to build a NAS. It’s primary function will be as a Plex media server streaming to 2 devices at most (1 at home and 1 at my office)

I also want to use it with Radarr and Sonarr and a Torrent Client

I currently use a synology DS 216+II and it operates well but it can’t stream higher resolutions well

Would this suffice?

As i am from Europe many parts on the guides are available but have to be shipped from the USA and that costs alot

So i sourced some parts that are available in the EU

I know QuickSync is very good for it so i looked at a processor supporting it

Are these components any good or should i replace some of them?
If I buy these components now I should be paying around 354 euros

[Intel Core i3-10320 Desktop Processor 4 Cores up to 4.6 GHz LGA1200]
[G.Skill Aegis DDR4 32GB (2x16GB) 3000MHz CL16 RAM-Kit XMP 2.0]
Sharkoon QB One
Power supply
Be Quiet! 500w SFX L, fully modular, 80+ gold
[ASRock Z490M Pro4 LGA1200 Micro-ATX]
Main Drive (for OS)
[fanxiang 512GB] → Cheap Chinese brand, any other good M2 drive priced the same?

What OS should i run for my operating needs? I dont plan on having extra HDD for backup only so all my drives should act as 1 storage
